He aha nā palena ʻehā o ka ʻoihana? Pehea ʻoe e ana ai?

ʻO nā palena ʻoihana ʻehāmahana, kaomi, ka nui o ke kahe ʻanaa mepae wai.

1. Mahana

ʻO ka mahana kahi waiwai kino e hōʻike ana i ke kekelē o ke anuanu a me ka wela o ka mea i ana ʻia. Wahi a ke ʻano ana o ka mea hana mahana, hiki ke hoʻokaʻawale ʻia i ke ʻano pili a me ke ʻano pili ʻole. ʻO ka mika pili no ke ana ʻana i ka mahana e komo pū ana me ka thermometer, ke kūpaʻa wela a me ka thermocouple. ʻO nā mea hana ana wela pili ʻole he optical pyrometer, photoelectric pyrometer, radiation pyrometer a me ka infrared thermometer.

2. Kaomi

ʻO ke kaomi i loaʻa ma luna o kekahi mea e komo pū ana me ke kaomi lewa a me ke kaomi o ka mea i ana ʻia (ʻo ke kaomi anakahi ma ke ʻano maʻamau) ʻelua ʻāpana, ʻo ka huina o nā ʻāpana ʻelua o ke kaomi ma luna o ka mea i ana ʻia ua kapa ʻia ʻo ke kaomi paʻa, a ua ana ʻia ke anakahi kaomi ʻoihana maʻamau e ka waiwai anakahi, ʻo ia hoʻi, P papa =P paʻa - kaomi lewa.

Hiki ke hoʻokaʻawale ʻia nā mea ana kaomi i ʻekolu mau ʻāpana: e like me ke kaumaha a me ke ʻano kaulike kaomi i ana ʻia, e ana pololei i ka nui o ka ikaika ma ka ʻāpana ʻāpana, e like me ke ana kaomi kolamu wai a me ke ana kaomi piston; Wahi a ke ʻano o ka ikaika elastic a me ke kaulike kaomi i ana ʻia, e ana i ka ikaika elastic i hana ʻia e ka deformation o ka element elastic ma hope o ke kaomi ʻana, e like me ke ana kaomi puna, ke ana kaomi bellows, ke ana kaomi diaphragm a me ke ana kaomi pahu diaphragm; E hoʻohana i nā waiwai kino o kekahi mau mea e pili ana i ke kaomi, e like me ke voltage a i ʻole ke kū'ē a i ʻole nā ​​​​loli capacitance i ke kaomi ʻia; No ka laʻana, nā mea ʻike kaomi.

3. Kahe

I ka hana ʻoihana a me ka kaohi ʻana, ʻo ka ʻike ʻana a me ka kaohi ʻana i nā palena kahe wai kekahi o nā palena maʻamau. Nui nā ʻano mika i hoʻohana ʻia e ana i ke kahe, me ka mika kahe ultrasonic, ka mika kahe electromagnetic, ka mika kahe throttling a me ka mika kahe volumetric.

4. Pae

ʻO ka pae wai e pili ana i ka pae o ka pae wai i loko o kahi pahu i hoʻopaʻa ʻia a i ʻole kahi pahu hāmama. ʻO nā mea hana maʻamau i hoʻohana ʻia no ke ana ʻana i ka pae wai he mika pae ultrasonic, mika pae aniani, mika pae kaomi ʻokoʻa, mika pae poepoe lana, mika pae buoy, mika pae papa magnetic flip ball lana, mika pae radar, mika pae radioactive, mika pae admittance alapine radio, a pēlā aku.
